LM2576HVT-5 (TO-220-5) Buck (Step Down) Switching Regulator

Description

1. IC Type: The LM2576HVT-5 is a switching voltage regulator IC.
2. Voltage Regulation: It is designed to provide a stable and regulated output voltage that is lower than the input voltage.
3. Fixed Output Voltage: The “5” in the part number indicates that the IC is specifically configured for a fixed output voltage of 5 volts.
4. Buck (Step-Down) Topology: The IC operates in a buck topology, which means it reduces the input voltage to produce a lower, regulated output voltage.
5. High Efficiency: Switching regulators are known for their high efficiency, which minimizes power dissipation and allows for smaller heat sinks.
6. Input Voltage Range: The LM2576HVT-5 can handle a wide input voltage range, making it suitable for a variety of applications.
7. Current Handling: It can deliver a moderate current level (typically in the range of several amperes) depending on the version and configuration.
8. Package Type: The TO-220-5 package is a through-hole package with five leads for easy mounting on a PCB. The additional leads are often used for better heat dissipation.
9. Adjustable Output Versions: While the LM2576HVT-5 is fixed at 5 volts, there are adjustable versions of the LM2576 series that allow you to set the output voltage to your desired level.
10. Applications: The LM2576HVT-5 is commonly used in various voltage regulation applications, such as power supplies for electronic devices, battery charging, and voltage conversion in both industrial and consumer electronics.
11. External Components: To set the output voltage and improve performance, the LM2576HVT-5 may require external components like resistors, capacitors, and inductors.
12. Datasheet: For detailed information on electrical characteristics, pin configuration, and recommended usage, it’s essential to refer to the datasheet provided by the manufacturer.
